【摘要】：目的评价全自动印模调拌机、半自动印模调拌机、手动调拌3种调拌方法调拌藻酸盐印模材料的气泡含量及物理性能。方法在同种条件下(室温、水粉比、蒸馏水温度),分别采用全自动印模调拌机调拌法、半自动印模调拌机调拌法、手动调拌法调制藻酸盐印模材料。比较各调拌方法所调制材料的气泡数量、气泡总面积、压应变值、弹性回复值、流动性。结果 3种调拌方法的气泡量和气泡面积之间差异有统计学意义。全自动调拌机调拌的材料气泡最少,半自动调拌机调拌的材料次之,手动调拌的材料气泡最多。3种调拌方法调拌的材料物理性能均符合国家相关标准,手工调拌法的弹性回复值低于半自动调拌法及全自动调拌法,全自动调拌法印模流动性最好。结论在本实验条件下,藻酸盐印模材料调拌方法对材料气泡含量及其物理性能有影响;不同调拌方法所调材料物理性能均符合国家相关标准,全自动调拌法所调材料性能最佳。
[Abstract]:Objective to evaluate the bubble content and physical properties of alginate impression materials in automatic, semi-automatic and manual mixing methods under the same conditions (room temperature, water / powder ratio). The temperature of distilled water was adjusted by the automatic die mixing machine, the semi-automatic impression adjusting machine and the alginate impression material by manual mixing. The bubble number of the materials modulated by each mixing method was compared. Results the difference of bubble volume and bubble area between the three methods was statistically significant. The material bubble of automatic mixing machine was the least. The material of semi-automatic mixing machine is the second, the material bubble of manual mixing is the most, and the material physical properties of three kinds of mixing methods accord with the relevant national standards. The elastic recovery value of manual mixing method is lower than that of semi-automatic mixing method and automatic mixing method. The method of adjusting alginate impression material has an effect on the bubble content and physical properties of the material. The physical properties of different blending methods are in line with the relevant national standards, and the fully automatic blending method is the best.
